Parameters 169
22.56 Critical speed 3 low Defines the low limit for critical speed range 3.
Note: This value must be less than or equal to the value
of parameter 22.57 .
0.00 rpm
-30000.00… 30000.00
rpm
Low limit for critical speed 3. See par.
46.01
22.57 Critical speed 3 high Defines the high limit for critical speed range 3.
Note: This value must be greater than or equal to the
value of parameter 22.56.
0.00 rpm
-30000.00… 30000.00
rpm
High limit for critical speed 3. See par.
46.01
22.71 Motor potentiometer
function
Activates and selects the mode of the motor
potentiometer.
See section Speed control performance figures in chapter
Program features.
Disabled
Disabled Motor potentiometer is disabled and its value set to 0. 0
Enabled (init at power-
up)
When enabled, the motor potentiometer first adopts the
value defined by parameter 22.72. The value can then be
adjusted from the up and down sources defined by
parameters 22.73 and 22.74.
A power cycle will reset the motor potentiometer to the
predefined initial value (22.72).
1
Enabled (resume
always)
As Enabled (init at power-up), but the motor potentiometer
value is retained over a power cycle.
2
Enabled (init to actual) Whenever another reference source is selected, the value
of the motor potentiometer follows that reference. After the
source of reference returns to the motor potentiometer, its
value can again be changed by the up and down sources
(defined by 22.73 and 22.74).
3
22.72 Motor potentiometer
initial value
Defines an initial value (starting point) for the motor
potentiometer. See the selections of parameter 22.71.
0.00
-32768.00… 32767.00 Initial value for motor potentiometer. 1 = 1
22.73 Motor potentiometer
up source
Selects the source of motor potentiometer up signal.
0 = No change
1 = Increase motor potentiometer value. (If both the up
and down sources are on, the potentiometer value will not
change.)
